I''m having a problem with the Shorewall firewall and CUPS printing interfering with each other. My Linux firewall machine is acting as both a CUPS server and client for all of my tests. Shorewall 2.0.13 CUPS 1.1.22-2 Linux kernel 2.6.9 CUPS was working fine to print to my Epson C84 (network connected via a Netgear PS101 print server using lpd://PS101.IP.address/raw ) until I

I have searched your FAQ''s and read the documentation on your site as well as googling. I am not able to figure this out. If you have any ideas can you please help. I am using the linux-ha failover with redundant firewalls. As part of the function of the linux-ha software consists a service called heartbeat which is a connection from each failover node through a serial cable or ethernet.

Hello! I am using shorewall shorewall-2.0.11-1 on fedora core2 (iptables-1.2.9-95.7). My box has 2 physical nic´s plus one virt. ipsec interface for a freeswan-vpn connection. A few days ago, portsentry spit out a lot of connections from windows clients (port 135, 445). Ooops. I review my shorewall settings but could not find a mistake. So I took a win-client and established a second

Hi, Trying to figure out why I cannot get access to dell.com Their site is up because I can browse using a different firewall. Trying to find out where the logs are located and what log files it would write to if it were to deny browsing to a website. I can see the [UNREPLIED] when using the shorewall status.

I''m very new to shorewall. My setup is IP Gateway (CentOS 4 + Shorewall) with 3 NIC cards. Shorewall works great on the firewall machine. Bind also works (local net machines get IPs fine). Under firestarter, all works great. With shorewall, the loc machines can not route past the firewall. They can connect to the firewall, but not past it. Exactly what information should I post to get

Good day to all. I don''t like to Post unless I am really stuck. Guess what? Redhat with Shorewall. Been using this for years. I have a new client that we have setup with Redhat and Shorewall. The problem is that his outside address (ETH0 = NET) is dynamic (i.e. DHCP enabled). All the rules work fine when we use a STATIC address on Eth0, so we know the rules, filters, tos etc work fine

Hi to all, I''d like to cut some log in /var/log/messages, as of netbios and ping entries. There are some particular rules in shorewall 1.4.5?

Also I don''t want to disable ping from loc to net, and from fw to net. Thanks

What exactly did you want to compare? `ss -tp` does not appear to show cmdline/process title. I enabled it for one server, but will have to wait for users to reconnect and for the issue to reappear there. In the meantime, on another server
